Resumo: | This paper presents an acoustic-prosodic analysis of entrain- ment in a Portuguese map-task corpus. Our aim is to ana- lyze how turn-by-turn entrainment varies with distinct structural metadata events: types of sentence-like units (SU) in consecu- tive turns (e.g. interrogatives followed by declaratives, or both declaratives), and with the presence of discourse markers, affir- mative cue words, and disfluencies in the beginning of turns. Entrainment at turn-exchanges may be observed in terms of pitch, energy, duration, and voice quality. Regarding SU types, question-answer turns are the ones with stronger similarity, and declarative-interrogative pairs are the ones where less entrain- ment occurs, as expected. Moreover, in question-answer pairs, there is also stronger evidence of entrainment with Yes/No and Tag questions than with Wh- questions. In fact, these subtypes are coded in distinctive prosodic ways (moreover, the first sub- type has no associated lexical-syntactic cues in Portuguese, only prosodic). As for turn-initial structures, entrainment is stronger when the second turn begins with an affirmative cue word; less strong with ambiguous structures (such as ‘OK’), emphatic af- firmative answers, and negative answers; and scarce with dis- fluencies and discourse markers. The different degrees of local entrainment may be related with the informative structure of distinct structural metadata events. |
